That computer has no Nvidia card. CUDA driver software for Nvidia CUDA hardware only. Why did you install the CUDA driver on a computer without CUDA hardware?

You will not be able to use the GPU-accelerated ray-traced 3D renderer on that computer. Don't wory about that, though. The ray-traced 3D renderer is a minor feature, and there are much better ways to use 3D in After Effects, including using Cinema 4D, which is part of the After Effects installation now:

I thought the CUDA cards just made the ray-tracing faster. I didn't know that AE ray-tracing would not function at all without one. Makes my new Mac Pro worthless for doing any ray-tracing in AE. Wonderful...

AE functions just fine without one if you do not install the Cuda Driver because the Cuda Driver makes AE crash if there is no CUDA Compatible NVIDIA card. Ray-traced rendering is just slower without the acceleration. BTW, even though I have a compatible card on my system I have only used the Ray-trace feature on about 3 projects for paying clients since the feature was introduced. I have other, faster, better ways of achieving the same results. If you really want to use something like Ray-traced rendering use the AtomKraft rendering plug-in with CC. It's not compatible with CC 2014 yet. It's the best $99 I ever spent on 3D in AE.
